The genetics of drought tolerance in wheat is poorly understood and the highly variable nature of rainfall in most rainfed environments makes genetic progress extremely difficult. Nevertheless, considerable improvement in the adaptation of wheat to dry areas has been made by plant breeders over the last 50 years. The adoption of modern varieties, however, has lagged behind that of irrigated areas and the percentage yield advance has been considerably lower.|Various strategies can be employed or developed to improve the efficiency of germplasm development targeted to dry environments. These strategies include the improved use of information, better characterization of testing locations, refinement of selection environments, implementation of suitable management practices, expansion of genetic variability, identification of drought adaptive traits and the implementation of molecular strategies, including the identification of QTLs and DNA fingerprinting.
